58 ILLINOIS STATE DAIRYMEN'S ASSOCIATION 



Guernseys or Jerseys are a little more economical producers 

 of butter fat than the other breeds. In part this is, how- 

 ever, offset by the fact that the other breeds will produce 

 more skim milk, which is a very valuable feed for growing 

 stock. 



Wherever whole milk is sold, either to cheese factories, 

 condenseries or for city milk trade, the Holstein cow pre- 

 dominates on account of the large flow of milk she produces. 

 While Holstein milk tests are lowest in butter fat of all 

 dairy breeds, the Holstein cow will produce enough milk in 

 a year to equal any, in many cases, exceed the butter fat 

 production of the other breeds. 



It costs more to produce 100 pounds of high-testing 

 milk than it does to produce 100 pounds of low-testing milk 

 and, until the consuming public will be educated to be will- 

 ing to pay for this difference in production cost, the Hol- 

 stein cow will predominate where whole milk is sold for city 

 consumption. 



So far the average yearly production of butter fat is 

 concerned, the difference is not so great between the differ- 

 ent breeds. Of the average of all the official records of 

 each breed up to several years ago, the Holstein led in both 

 milk and butter fat production, averaging 14,974 pounds of 

 milk and 505 pounds of butter fat with an average test of 

 3.42 per cent fat. 



The Guernsey breed averaged 9,030 pounds of milk 

 and 453 pounds of fat with an average of a little over five 

 per cent. 



The Jersey breed averaged 7,931 pounds of milk and 

 424 pounds of butter fat, with an average of 5.35 per cent 

 fat. 



The Brown Swiss averaged 10,931 pounds of milk and 

 437 pounds of fat with an average of about four per cent 

 fat. 



The Ayrshire breed averaged 9,621 pounds of milk and 

 381 pounds of fat with an average of nearly four per cent 

 fat. 



To successfully raise a good dairy calf, it is essential to 

 keep the calf growing from the time it is born until it be- 

 comes a mature cow.
